Thanks for your answer Allura. I will discuss this with my dr. I don't know why she thinks the xopenex is harder on you than albuterol. She told me Xopenex makes you much more jittery and she said if albuterol is helping me then I should stick with it. My concern is with having to use the inhaler everyday, but you did explain that. I honestly think that a lot of my problems are due to my dog, poor soul. I think all the odor from him and the smell from him being incontinent is aggravating me. Unfortunately we are having him put to sleep next Tues. So after a few days of him being gone and the house cleaned I will be able to tell if I am better. And the dog is very old, almost 17 and in poor health so this was planned despite my breathing problems. I will post again about this and let you know how I am doing and if i improve. Thanks again for being so helpful, you really seem to know so much about asthma and allergies.
